Allergy serology

Below is a complete list of the specific IgE tests performed in Oxford. For other allergens please contact Laboratory Immunology on (01865) 225995.

Specific IgE tests are available to a wide range of antigens. However, the Gold Standard is a thorough clinical history along with skin prick tests except in the following cases:

  • Small children
  • Those with extensive skin involvement that precludes skin testing
  • Where there is a risk of anaphylaxis

In the absence of a strong clinical history, Specific IgE analysis is of little significance.

Blanket requests for 'RAST testing' will be ignored.

Please give full details of suspected allergens and symptoms. Tests for specific IgE to penicillin are not reliable in diagnosing immediate type hypersensitivity to this drug.

For further information on Food Allergy in children and young people, please see the latest NICE Guidelines from February 2011 (CG116)
